The BUG below is clearly triggered by the nvidia modules, which cannot be debugged by Fedora developers. If you believe you can reproduce this bug on a machine w/o any external modules, i.e. using only xorg's nv driver (also comment the nvidia kernel module out of /etc/modprobe.conf, your kernel needs to report that it is not tainted), then please bugzilla and post a message here. > This morning one of them had X frozen and I found this in the log > > Sep 24 12:56:35 septem kernel: ------------[ cut here ]------------ > Sep 24 12:56:35 septem kernel: kernel BUG at mm/page_alloc.c:792! > Sep 24 12:56:35 septem kernel: invalid operand: 0000 [#1] > Sep 24 12:56:35 septem kernel: SMP > Sep 24 12:56:35 septem kernel: Modules linked in: snd_pcm_oss snd_mixer_oss snd_intel8x0 snd_ac97_codec snd_pcm snd_timer snd_page_alloc gameport snd_mpu401_uart snd_rawmidi snd_seq_device snd soundcore nvidia(U) nfs lockd parport_pc lp parport autofs4 sunrpc e1000 floppy sg scsi_mod microcode dm_mod uhci_hcd ehci_hcd button battery asus_acpi ac ext3 jbd > Sep 24 12:56:35 septem kernel: CPU: 2 > Sep 24 12:56:35 septem kernel: EIP: 0060:[<02140502>] Tainted: P > Sep 24 12:56:35 septem kernel: EFLAGS: 00013256 (2.6.8-1.521smp) > Sep 24 12:56:35 septem kernel: EIP is at __free_pages+0x20/0x4c > Sep 24 12:56:35 septem kernel: eax: 00000000 ebx: 00000000 ecx: 03640240 edx: 03640240 > Sep 24 12:56:35 septem kernel: esi: 39710cf0 edi: 00000010 ebp: 00000000 esp: 39710ce8 > Sep 24 12:56:35 septem kernel: ds: 007b es: 007b ss: 0068 > Sep 24 12:56:35 septem kernel: Process X (pid: 2344, threadinfo=39710000 task=37e998b0) > Sep 24 12:56:35 septem kernel: Stack: 0368a938 0211a5a9 03368378 0360c258 03b4d100 00000010 03b4d100 00000010 > Sep 24 12:56:35 septem kernel: 022080c6 00000010 00000010 39710d60 39710ed8 43238d1c 434f3e20 00000010 > Sep 24 12:56:35 septem kernel: 39710d60 41705bc0 00000010 00000041 41706ec0 434f3e20 432375fe 39710e80 > Sep 24 12:56:35 septem kernel: Call Trace: > Sep 24 12:56:35 septem kernel: [<0211a5a9>] global_flush_tlb+0xe9/0xf3 > Sep 24 12:56:35 septem kernel: [<022080c6>] agp_allocate_memory+0x8c/0x93 > Sep 24 12:56:35 septem kernel: [<43238d1c>] KernAllocAGPPages+0x6c/0x167 [nvidia] > Sep 24 12:56:35 septem kernel: [<432375fe>] nv_alloc_pages+0xb9/0x310 [nvidia] > Sep 24 12:56:35 septem kernel: [<43096a5b>] _nv004819rm+0x4b/0x88 [nvidia] > Sep 24 12:56:35 septem kernel: [<43078882>] _nv001629rm+0x6e/0x78 [nvidia] > Sep 24 12:56:35 septem kernel: [<43078841>] _nv001629rm+0x2d/0x78 [nvidia] > Sep 24 12:56:35 septem kernel: [<4305b8d2>] _nv006380rm+0x16/0x3c [nvidia] > Sep 24 12:56:35 septem kernel: [<4306d1ca>] _nv001734rm+0x36/0xe0 [nvidia] > Sep 24 12:56:35 septem kernel: [<43062799>] _nv001226rm+0x121/0x138 [nvidia] > Sep 24 12:56:35 septem kernel: [<4305ba3e>] _nv006349rm+0xaa/0xd8 [nvidia] > Sep 24 12:56:35 septem kernel: [<4307fe9d>] _nv002132rm+0x31/0x48 [nvidia] > Sep 24 12:56:35 septem kernel: [<43062552>] _nv001231rm+0x1ce/0x2f4 [nvidia] > Sep 24 12:56:35 septem kernel: [<4306dbe6>] _nv001659rm+0x26/0x2c [nvidia] > Sep 24 12:56:35 septem kernel: [<4307872e>] _nv001633rm+0x12/0x18 [nvidia] > Sep 24 12:56:35 septem kernel: [<4305f0fa>] _nv003453rm+0x86/0xd8 [nvidia] > Sep 24 12:56:35 septem kernel: [<4307e1c5>] rm_change_res_mode+0x69/0x8c [nvidia] > Sep 24 12:56:35 septem kernel: [<4307eefb>] _nv001139rm+0x16b/0x4b8 [nvidia] > Sep 24 12:56:35 septem kernel: [<02158793>] rw_vm+0x2df/0x331 > Sep 24 12:56:35 septem kernel: [<4307e147>] rm_ioctl+0x23/0x38 [nvidia] > Sep 24 12:56:35 septem kernel: [<43236514>] nv_kern_ioctl+0x31c/0x367 [nvidia] > Sep 24 12:56:35 septem kernel: [<0216d078>] sys_ioctl+0x23d/0x2a0 > Sep 24 12:56:35 septem kernel: [<0215a97b>] filp_close+0x59/0x5f > Sep 24 12:56:35 septem kernel: [<0215aa21>] sys_close+0xa0/0xd3 > Sep 24 12:56:35 septem kernel: Code: 0f 0b 18 03 01 f6 2e 02 f0 83 41 04 ff 0f 98 c0 84 c0 74 16 > Sep 24 12:57:50 septem kdm: :0[31429]: Cannot connect to :0, giving up > Sep 24 12:57:50 septem kdm[2192]: Display :0 cannot be opened > Sep 24 12:57:50 septem kdm[2192]: Unable to fire up local display :0; disabling. > > > > Ciao, > GianPiero -- Axel.Thimm at ATrpms.net
